It's a mad dash to the finish line. Valley candidates are hoping to snag those extra votes hours before the polls open for the primary election.

There are many locations across Fresno County where you can cast your vote on Tuesday. But a lot of people are concerned that Fresno County voters won't make it out for the primaries.

The streets are littered with signs and postboxes stuffed full of mailers. It's hard to miss there's an election taking place. But so far, the clerk's office has only accounted for less than 15 percent of absentee ballots.

"We need each and every one of them to come out and cast a ballot," said Stuart Weil, who is one of a handful of volunteers calling nearly 4,000 Fresno County voters on Monday.

"You'd be surprised at how many people forget to go to the polls, so this is an important aspect in get out and vote," said Weil.

It's the final leg in the campaign marathon to get their choice candidate in office. Whether they're flying through the sky during rush hour or waving on top of an overpass, campaign volunteers know how critical these final hours are for office-seekers.

"These guys are all going home tonight and it's critical that we get this vote out; it's only going to be about 15 or 18 percent, 20 at the most," said Dallas Debatin, a campaign volunteer.

The primary election is the pre-cursor for November, so many of the candidates chosen on Tuesday have to get right back to work to win the general election. But same-party candidates like Lisa Sondergaard Smittcamp and Elizabeth Egan, who are both Republicans and running for district attorney, know by Tuesday if they've won the race.
